Does the number of leads with inverted T waves predict in-hospital complicated events in patients with acute pulmonary embolism?
The presence of inverted T waves in 7 or more leads on admission ECG is a strong independent predictor of early complications in patients with acute pulmonary embolism.
Odds Ratio: 16.8 (95% CI 1.17–212.8)
Absolute Event Rate: 46% vs 0%
p-value: p=0.037
BACKGROUND: The significance of inverted T waves remains unclear in patients with acute pulmonary embolism (PE). METHODS AND RESULTS: The relationship of the number of leads with inverted T waves to the severity of PE in 40 patients with acute PE was studied. Patients were classified into 3 groups according to the number of leads with inverted T waves on the admission electrocardiogram (ECG): 15 patients, or=7 leads (group H). In groups L, M and H, the rates of right ventricular dysfunction on echocardiography were 47%, 92% and 100% (por=7 leads on the admission ECG (OR 16.8, p=0.037) were the only independent predictors of in-hospital complicated events. CONCLUSIONS: The number of leads with inverted T waves may be a useful and simple marker of increased risk for early complications in patients with acute PE.
أجرى كوسوجي وزملاؤه (صن) دراسة قائمة على مجموعة في الانصمام الرئوي الحاد (n=40). تم تقييم موجات T المقلوبة في ≥7 قنوات على تخطيط القلب عند admission مقابل موجات T المقلوبة في ≤6 قنوات بناءً على الأحداث المعقدة أثناء الاستشفاء (الموت أو الحاجة لدعم الكاتيكولامين، الإنعاش القلبي الرئوي، أو الدعم القلبي الوعائي الآلي) (OR 16.8، 95% CI 1.17-212.8، p=0.037). كان وجود موجات T المقلوبة في ≥7 قنوات على تخطيط القلب عند admission يتنبأ بشكل مستقل بالأحداث المعقدة أثناء الاستشفاء لدى مرضى الانصمام الرئوي الحاد (OR 16.8).
